Where to find the official datasheet

For pinout diagrams, electrical characteristics, timing diagrams, and exact memory/peripheral counts for specific NPCT750 variants, consult the manufacturer’s official datasheet and application notes.

Key features

• Core: 32-bit ARM Cortex-M0+ (single core) running up to ~48 MHz (typical for M0+ class).
• Memory: On-chip flash (commonly 32–128 KB range) and SRAM (commonly 4–16 KB); exact sizes vary by NPCT750 variant.
• Peripherals: Multiple UART/USART, I2C, SPI, PWM, ADC (10–12 bit), and timer/counter modules for real-time tasks.
• Low-power modes: Several sleep and deep-sleep modes to minimize battery drain in portable designs.
• Security: Basic hardware security features (secure boot, flash protection, option bytes/lock bits); may include cryptographic accelerators on some variants.
• Package options: Small-outline packages (QFN, LQFP) suitable for compact PCBs.
• Operating voltage: Typical single-supply range around 1.8–3.6 V.
• Temp range: Industrial and commercial options (e.g., –40 °C to +85 °C for industrial).

10. PCB Layout and EMC Guidance

• Place decoupling caps (< 5 mm) near each VDD pin; use 0.1 μF ceramic + bulk 4.7–10 μF.
• Keep high-speed traces short; route differential or clock lines with controlled impedance when needed.
• Separate noisy power supplies from analog sections; use ground pours with a single star ground for sensitive analog pins. Actionable: include ESD diodes on external connectors, add series resistors on sensitive signal lines, and follow recommended ground stitching/thermal pad soldering for QFN packages.

Key Features

• Precision Metering: The NPCT750 is typically designed for revenue-grade accuracy (often Class 0.3 or 0.6), ensuring precise data collection for billing and energy auditing.
• Wide Current Range: This series covers a broad spectrum of primary current ratings, generally ranging from 50 Amps to 1200 Amps. This versatility allows it to be utilized in diverse settings, from small commercial panels to large industrial switchgear.
• Compact Design: The transformer features a compact, rectangular design with a center window, facilitating easier installation in crowded switchgear or panelboards where space is at a premium.
• Safety Ratings: The unit is rated for a maximum system voltage of 600V, making it suitable for standard low-voltage distribution systems. It also features high withstand ratings for thermal and dynamic stress, ensuring durability during short-circuit events.
